Old enough to marry

A lot of my friends have become mothers and others are married. My mother does not seem to worry that her daughter(me)is getting older by the day. she says I can stay with her and apa as long as I am single. And she feels I will be living many years with her which means she feels I will not marry any sooner.
A few friends do worry for me and I have a maternal aunt who worries a lot. She says I am old enough to marry and once i get older I will remain single forever.

A few years back I did have a dream of marrying the person I was with and after he left me for some other girl that dream was shattered. However one does not stop dreaming and nether did I. I met a new guy and yes I had dreams of marrying him too. I won't say if I or he cheated but it was our decision because we realized, we were not meant be.

Since then I never though of marrying anyone. But when a girl is of my age the first question put up to you by a stranger, cousin, friend be it anyone is, "are you married,?" The moment I say no, the immediate question is, "aren't you old enough to marry,?"

Sometimes I choose not to answer, sometimes I lie and sometimes I tell the truth.

I know I am old enough to marry but can't I be on my own?
